Seem to know what they’re doing, so DDK, but no subtlety to play (no kikashi, plays a bit clumsy and obvious)
Bigger plays missed, not much attention to sente. so my guess is … is… 16k
My first thought was that this was someone playing against himself so I’ll stick to that even though OP said ‘Both players’. As for rank…12kyu with my theory allowing for some of the peculiar moves.
maybe 10-12k, judging from moves in endgame such as move 128. also moves like move 20 and move 63 feels a bit slow since white won’t really be able to cut… it kinda makes me feel like a player is playing himself. (in particular, n18 and s10 gave me a similar feel? and they didn’t really follow up on those moves.
The amount of opening mistakes alone are stunning. A 1D should be able to wreck both of these players. However I do know that people are crazy, so my guess is 5kyu, which is already quite high.
They’re not opening mistakes, they’re moves deliberately chosen to confuse either opponent or this audience.
The game is weird, because neither player makes terribly unreasonable moves. It’s too calm, as if someone was playing against himself, thus not feeling the need to “win”. The opening is irrelevant. Reading is either dan level or it’s a correspondence game with both players always deflecting each other’s intentions.
Then there are clearly point-losing moves like 133, 252 which are just bad.
